public class CommitActionsAttribute extends AbstractActionsAttribute implements CommitAction
The value of this attribute is a semicolon separated list of commands, where each command gives a destination and a value. The actions are given by calling setExpression() with a string of the form:
command; command; ...where each command has the form:
destination = expressionwhere destination is variableName, where variableName is either a variable or parameter of the FSM actor, or a variable or parameter of a refinement state. To give a variable of a refinement state, use a dotted name, as follows:
refinementStateName.variableName
The expression is a string giving an expression in the usual Ptolemy II expression language. The expression may include references to variables and parameters contained by the FSM actor.
The destination can also be a port, however, this is discouraged. Commit actions are not executed until postfire(), and the Ptolemy II abstract semantics requires that outputs be produced in fire(). Nonetheless, this is supported. In this case, the destination is either
portNameor
portName(channelNumber)Here, portName is the name of a port of the FSM actor, If no channelNumber is given, then the value is broadcast to all channels of the port. If destination name is given where there is both a port and a variable with that name, then the port will be used.
